Say: "O men! I am sent unto you all, as the Messenger of Allah, to Whom belongeth the dominion of the heavens and the earth: there is no god but He: it is He That giveth both life and death. So believe in Allah and His Messenger, the Unlettered Prophet, who believeth in Allah and His words: follow him that (so) ye may be guided." 158 And of Musa's people was a party who guided (people) with the truth, and thereby did they do justice. 159 We divided them into twelve (different) tribes. When his people asked for water, We said to Moses: "Strike the rock with your staff;" and behold, twelve springs of water gushed forth, so that each of the tribes had a place of its own to drink; and We made the clouds spread shade over them and sent for them manna and quails (and said): "Eat of the good things We have provided for you." But (by disobeying) they did not harm Us, they harmed themselves. 160 When it was said to them: 'Dwell in this village, and eat of whatever you please; and say, "Unburdening" and enter the gate prostrating, We will forgive you your sins and increase the gooddoers' 161 The wicked among them changed and perverted the word We had spoken to a word unpronounced; so We sent from heaven retribution on them for all their wickedness. 162
